Yeah need to get a new one - how did you get on this morning mate?
Yes if you do see a drain with everything off, you need to start pulling fuses until you find the circuit showing a drain!
I guess it will show the bonnet as open & alarm might not set, not certain on this, as never had to try it on an Audi.
Researching I found this - will check hazard switch, but is it worth pulling the alternator wires and see if this helps starts?

You can see the boot light looking down through the glass....
I'm going to check my hazard switch now.....
Will also check glovebox light now as well.....
In terms of the wire to the alternator from the battery - I see a big think red cable that goes towards the ECU and to the left hand side of the bay - but there is also a wire that goes right under a scuttle tray...
Ooh the plot thickens! So could a dodgy alternator diode leak power back to the hazard switch?The smaller wire to the alternator should be the wire back to the dash warning light!
My real name is David, although I am actually a sprinter as well (as in the athlete kind, not the Mercedes van)So Sprinter (whats ya name!) I'm going to unplug the battery negative altogether tonight and leave it off.....then reconnect and try starting in the morning...
Are you going to connect a meter to see it there's any draw??Unplugged now......plugged in and alarm went off and keys lost remote central locking but I can redo that easily tomorrow.....
So will test and see how we get on...

Oops, that was meant to say 12.49V. Don't worry I haven't been wiring up my batteries in 24V configuration!I don't get this 21.49v you would only see that if they were wired in series, in parallel you should only be seeing 13+ volts, if you were putting that voltage through the system you would fry the electrics??
Interesting, so maybe the battery drain is a red herring...
I havn't got a multimeter so my test is purely about seeing is the battery drain is a red herring or not I guess. If I hook it up tomorrow and find it all OK once plugged in then it can't be a drain issue surely?
